Q: Do both cards have display outputs?

A: No. The NVIDIA Tesla K80 has no display outputs, making it unsuitable as a primary display adapter. The AMD Radeon RX 7600 XT includes 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs.

Where Each One Wins

The data splits this comparison into two very different use cases. The AMD Radeon RX 7600 XT wins every head-to-head benchmark recorded in the database, and it wins by enormous margins. In Geekbench OpenCL, the RX 7600 XT scores 92426 against the Tesla K80's 18620, a delta of 79.9%. In Geekbench Vulkan, the AMD card scores 48366 versus 19111, a 60.5% advantage. If the workload is graphics, compute, or modern API acceleration, the RX 7600 XT is the clear choice.

The NVIDIA Tesla K80, however, wins in one specific sense: its average benchmark score across all recorded tests is higher than the AMD card's. The Tesla K80 averages 18866 across its two benchmarks, while the RX 7600 XT averages 17083 across its ten benchmarks. This is partly a function of benchmark selection, but the database also shows the Tesla K80 at the 63rd percentile versus the RX 7600 XT at the 60th. For workloads that resemble the Tesla K80's specific test profile, namely Geekbench OpenCL and Vulkan, the AMD card dominates, but the K80's overall standing in the database remains slightly higher.

The Tesla K80 also wins on transistor density and die size considerations. It packs 7,100 million transistors on a 561 mm² die at 12.7M transistors per mm². The RX 7600 XT packs 13,300 million transistors on a much smaller 204 mm² die at 65.2M transistors per mm². The AMD card is the denser design, but the Tesla K80 uses a larger physical die, which historically matters for certain compute deployments.

For gaming, the RX 7600 XT is the only realistic option because the Tesla K80 has no display outputs. For compute-only environments where the card sits in a server or workstation without needing to drive a monitor, the Tesla K80's higher average score and established Kepler architecture might still have a place, though its compute performance is far lower in the recorded tests.

Architecture Differences

The NVIDIA Tesla K80 is built on the GK210 chip using Kepler 2.0 architecture, fabricated on a 28 nm process at TSMC. It belongs to the Tesla Kepler generation (Kxx) and is the successor to Tesla Fermi, with Tesla Maxwell following it. The AMD Radeon RX 7600 XT uses the Navi 33 chip with RDNA 3.0 architecture, codenamed Hotpink Bonefish, part of the Navi III (RX 7000) generation. It is fabricated on a 6 nm process, also at TSMC, and sits between Navi II and Navi IV in AMD's product line.

The manufacturing difference is stark. The Tesla K80 uses a 28 nm process with 7,100 million transistors on a 561 mm² die, yielding a transistor density of 12.7M per mm². The RX 7600 XT uses a 6 nm process with 13,300 million transistors on a 204 mm² die, yielding 65.2M per mm². The AMD card crams almost twice as many transistors into roughly a third of the silicon area.

Architecturally, the two cards diverge completely. The Tesla K80 has 2496 shading units, 208 TMUs, and 48 ROPs. It has no ray tracing cores and no tensor cores. The RX 7600 XT has 2048 shading units, 128 TMUs, and 64 ROPs, but it also includes 32 ray tracing cores. This means the AMD card supports hardware-accelerated ray tracing while the NVIDIA card does not. The RX 7600 XT also has a higher pixel rate at 176.3 GPixel/s versus the Tesla K80's 42.85 GPixel/s, and a higher texture rate at 352.6 GTexel/s versus 171.4 GTexel/s.

The memory architectures reflect their different eras. The Tesla K80 uses GDDR5 with a 384-bit bus, while the RX 7600 XT uses GDDR6 with a 128-bit bus. The narrower bus on the AMD card is compensated by faster memory clocks, resulting in higher overall bandwidth. The API support also shows the generational gap, with the RX 7600 XT supporting DirectX 12 Ultimate and Vulkan 1.4, while the Tesla K80 is limited to DirectX 12 (11_1) and Vulkan 1.2.175.

Specification Differences

The clock speeds differ substantially. The Tesla K80 runs at a 562 MHz base clock and 824 MHz boost clock, with memory at 1253 MHz (5 Gbps effective). The RX 7600 XT runs at 1980 MHz base, 2470 MHz game clock, and 2755 MHz boost, with memory at 2250 MHz (18 Gbps effective). The AMD card operates at more than triple the boost clock of the NVIDIA card.

Memory capacity and type differ: 12 GB GDDR5 for the Tesla K80 versus 16 GB GDDR6 for the RX 7600 XT. Bandwidth is 240.6 GB/s versus 288.0 GB/s in favor of AMD. The bus widths are 384-bit versus 128-bit, but the faster GDDR6 memory on the AMD card wins on throughput.

The TDP is 300 W for the Tesla K80 and 190 W for the RX 7600 XT. Both use a single 8-pin power connector and are dual-slot cards, but the suggested PSU is 700 W for the NVIDIA card and 450 W for the AMD card. The bus interface differs as well: PCIe 3.0 x16 for the Tesla K80 versus PCIe 4.0 x8 for the RX 7600 XT.

Physical dimensions favor the AMD card. The Tesla K80 is 267 mm (10.5 inches) long with no listed height or width. The RX 7600 XT is 204 mm (8 inches) long and 115 mm (4.5 inches) tall. Display outputs are a major differentiator: the Tesla K80 has none, while the RX 7600 XT has 1x HDMI 2.1a and 3x DisplayPort 2.1.

The production status separates them further. The Tesla K80 is end-of-life and was released in November 2014, while the RX 7600 XT is active and was released in January 2024. The RX 7600 XT has a launch MSRP of 329 USD. The Tesla K80 has no launch MSRP recorded in the database.

Head-to-Head Benchmarks

The database records two head-to-head benchmark comparisons between these cards, and the AMD Radeon RX 7600 XT wins both.

In Geekbench OpenCL, the RX 7600 XT scores 92426 against the Tesla K80's 18620. The delta is 79.9% in favor of AMD. This is the largest single gap in the comparison. The Tesla K80's OpenCL score is lower than every one of its nearest rivals: the GeForce RTX 2070 scores 18789 (0.4% above the K80), the RTX 2000 Ada Generation scores 18954 (0.5% below the K80), the Quadro K6000 scores 19030 (0.9% below), and the Radeon RX 6600 scores 19036 (0.9% below). The Tesla K80 is essentially at parity with these cards, all clustered within a 1% range, which makes the RX 7600 XT's OpenCL lead look even more decisive.

In Geekbench Vulkan, the RX 7600 XT scores 48366 versus the Tesla K80's 19111, a 60.5% advantage for AMD. The Tesla K80's Vulkan score of 19111 is actually close to its OpenCL score of 18620, suggesting the Kepler architecture does not scale much between these APIs. The RX 7600 XT, by contrast, shows a significant drop from its OpenCL score of 92426 to its Vulkan at 48366, yet it still more than doubles the Tesla K80's Vulkan result.

The RX 7600 XT's nearest rivals in the database give context beyond the head-to-head comparison: the GeForce GTX 690 averages 17037 (0.3% below the RX 7600 XT), the Radeon HD 7970M averages 17019 (0.4% below), the GeForce RTX 3070 averages 17208 (0.7% above), and the Tesla M4 averages 16932 (0.9% below). The RX 7600 XT sits within 1% of these cards, which again places it far ahead of the Tesla K80 in raw compute tests.

The Verdict

Pick the AMD Radeon RX 7600 XT if you need a card that can actually drive displays, play modern games with DirectX 12 Ultimate support, and run ray-traced workloads. The data shows it wins both recorded benchmarks by 79.9% and 60.5%, respectively. It offers 16 GB of GDDR6 memory with 288.0 GB/s bandwidth, 32 ray tracing cores, and a 190 W TDP with a 450 W suggested PSU. The RX 7600 XT also has a launch MSRP of 329 USD and is an active product.

Pick the NVIDIA Tesla K80 if you specifically need a Kepler-generation compute card with no display output requirement and want the higher average benchmark score in the database. The K80 averages 18866 versus the RX 7600 XT's 17083, and it sits at the 63rd percentile of all GPUs versus the AMD card's 60th. Its nearest rivals in the database, including the GeForce RTX 2070 and Quadro K6000, are all within roughly 1% of its average score, suggesting it remains competitive in its specific compute niche.

For virtually every practical purpose, the RX 7600 XT is the stronger card. Its FP32 compute of 22.57 TFLOPS dwarfs the Tesla K80's 4.113 TFLOPS. Its pixel rate of 176.3 GPixel/s and texture rate of 352.6 GTexel/s are far ahead. Its 6 nm process with 65.2M transistors per mm² represents a much more modern design. The Tesla K80 is end-of-life, uses a 28 nm process, and lacks display outputs entirely. The only scenario where the K80 makes sense is a specialized compute deployment where its higher average database score and established Kepler ecosystem matter more than raw performance, modern API support, or power efficiency.
